GPS Ndrive Touch SE Unlock Error

Hello friends,
I have in my hands a gps Ndrive Touch SE, I wanted to release and install a menu with 2 browsers entering the wince and modifying the windows start register

HKEY_LOCAL_MACHINE ~> System ~> Explorer ~> Shell Folders ~> StartUp

changing from ("\ Windows \ StartUp") to ("\ SDMMC \ StartUp)

Now, start and a "desktop" icon appears that can not be accessed. I suppose it is due to having changed the start route.
Before I could access wince by creating an "explorer.exe" file in the root of the sd card, now I can not do it anymore, I can not access wince.

Is there any solution to this?
Does anyone have the firmware of this device?wince 5.0 resolution 320x240

my problem arose when following the following tutorial:[Only registered and activated users can see links. ]
